Hey,

Power FC is locked since its last tune by the previous owner. How do I unlock it? Do I need the special software or can it be done via the hand controller?

There's no power fc tuner here in rocky and I wanna upgrade the afm's.....

Cheers,

Chris.

Thats very interesting to know .

Is it only the fc's that croydon have tuned or does this happening when with every fc that has been locked?

How is croydon able to lock it and then when the fc is accessed by another datalogit or axcel software it get's reset to initated setting?

Not with mine and FC-datalogit; mine was last tuned by them about 3 years ago and I unlocked it after a hardware change about 2 years ago.

Maybe they're doing something different now...

this is a bug within FC-Edit itself, its not able to "see" the values so it overwrites them with its default when you hit update

this is common and very obvious with the injector settings, they get scrambled when you unlock it

i think its also different for different verison of the FC-Edit and PFC models, ie RB25 mangles the injector settings

and say RB26 may mangle other stuff, its just interface / validation bugs in their code (datalogits)

you would be able to unlock / relock a PFC with no dataloss with the correct sequence and code (ie: apexi FC Pro)

croydon is able to lock it as they have the datalolgit software, which you can lock a PFC tune

it gets "reset" when you unlock it due to an interface bug, its not croydons fault you have to reset it, once unlocked

croydon lock PFC tunes i guess to "protect" the user from doing something stupid on the hand controller

i guess that defeats the point of a stand alone engine management system, to allow you to manage it

nah it doesnt, should just be able to save the tune, then uncheck the "protect" ticks in settings 2 screen. i have a few customers come in with locked PFC's.... i also lock them on customer request as many have 'fast and furious" fingers and dont trust themselves... :D

      I don’t really have any ideas how to set the timing on the CAS 😂, sounds like the top, sounds like it maybe misfiring as well as ticking,  got the box sorted 😌, must of been a air bubble on the clutch side

      Use a 2' length of hose (that's 2 foot, not 2 inches) as a stethoscope to localise the source of the ticking. From cam covers? From exhaust or turbo manifold gasket? From injectors? From lower down in the engine? Etc. Use a timing light to set the timing. Put Redline Lightweight Shockproof in the box. It's not the very best thing for the box, but it will take a box that refuses to engage a gear with other oil, and make it engage a gear. I had to put it in when I installed the R33 box I have in my car. It would not select ANY gear when running. Smurf jizz made it work. That was >10 years ago and I still use it. I'm stuck with it now. Failing that - rebuild the box.

      Well done Duncan. The fuel tank bulkhead lid is also in great condition (some of mine were stuffed). These are now out of production and good ones like that are becoming hard to come by.
